STORAGE BATTERY.

T o @ZZ whom it may concern Be it known that I, vHARRY MGCREARY, citizen of the United States of America, re-A siding at Youngstown, in the county of Mahoning and State of Ohio, have invented certain new and useful Improvements in Storage Batteries, of which the following tive plates and also to keep the multiples comprising the plate from buckling.

With these and other objects in view this invention consists of certain novel combinations, constructions, and arrangements of parts as will be hereinafter fully described and claimed.

In the accompanying drawing:

Figure l is a perspective view, partly in section, of the sto'rage battery.

Fig. 2 is a detail sectional view showing a portion ofthe positive plate with rubber retainers for retaining activematerial on grids.

Fig. 8 is a detail view showing a portion of the rubber retainer.

Referring to the drawing by numerals it will be seen that I have provided a jar 1. At the bottom of the jar l, I have provided supports 2 for the plates within the jar 1. TheseV supports leave a chamber 3 into which the sediment and settlings may sink and thereby keep the plates free from such sediment orsettlings.

The negative plates 4 are constructed of a plurality of grids spaced apart by means of a strap 6 at the bottom of the plate 4 and a strap 7 at the topvof vthe plate 4.

The straps 7 are connected by a strap 8 which 'connects the negative plates 4. At-

Specification of Letters Patent. l Patentedllwacl'. 1, ,1921 'Y Application med May 1o,

tached to the negative plate strap 8 is a binding post 9. The positive plates 10 are constructed of a .plurality'of grids 11 which are spaced apart and held from buckling and also retain the active materialsv on the gridsY 11 by means of a perfectedfrubber member 12, provided with ribs 13 used as a brace to hol-d the perforated material of the grids 11.

It will be seen by referring to Figs. l and 2 that the positive plates 10 are composedV of a plurality of grids 11 interspersed by the perforated rubber retainers 12, and braced by means of the ribs 1 3. These grids l1 are secured by means of straps 14 at the bottom- 1. In a device of the classl described the combination of negative plates comprising a plurality of grids spaced apart, a strap binding said grids at the top, a strap binding said grids at the bottom, a strap connecting said negative grids with a series of positive plates, comprising a plurality of grids, spaced apart, a perforated rubber retainer, ribs on said perforated rubber retainer, straps binding the lower edges of .Y

said grids and the upper edges of said grids,` a strap connecting said positive plates, sub stantially as described.

2. In a device of the class described, a

series of positive plates, Vcomprising a plus' Y K rality of grids, spaced apart, aperforated rubber retainer,' ribsV on .said perforated rubber retainer, straps ybinding the lower edges of said grids and the upper'edges of said grids, a strap connecting said positive plates, substantially as described for the purpose set forth. l f

In testimony whereof I aiiiX my signature.
